Excellent quality olive oil is incredibly easy to find, if you're buying bottom barrel junk then that's on you.
New vehicle prices when adjusted for inflation have not risen at all; when adjusted for features/comfort/reliability/luxury they've fallen a ridiculous amount.
Same for clothing. My $14.88 Walmart jeans lasted for years before I sized out of them. My $15 t-shirts from Target are going strong. I recently got $15 gym shirts from Target which seem to be excellent quality, thick material and good stitching. The cheap gym shorts I bought literally 10 years ago are still in perfect condition. And again you need to adjust for inflation when comparing to the older clothing you're talking about.
The OLED TV I got for $2700 a few years ago is now closer to $2k and has superior specs. And again, way superior to more expensive TVs from a decade or two ago.
For car repair... what repair do you even need on a modern Japanese car? They just work forever if you do even the bare minimum maintenance. And honestly even if you neglect that maintenance. Yes labor costs have gone up but that's not relevant to this discussion.
All your other complaints are about software which isn't really relevant to this discussion.
Honestly all of this sounds like a "you problem." No offense.
